ABOUT WWVB (radio-controlled time)
The NIST (National Institute of Standards and Technology-Time and
Frequency Division) radio station, WWVB, is located in Ft. Collins,
Colorado and transmits the exact time signal continuously throughout
the United States at 60 kHz. The signal can be received up to 2,000
miles away through the internal antenna in the Wireless Weather
Station. However, due to the nature of the Earth’s Ionosphere, recep-

tion is very limited during daylight hours. The Wireless Weather Station will search for a signal every night when reception is best. The
WWVB radio station derives its signal from the NIST Atomic clock in
Boulder, Colorado. A team of atomic physicists continually measure
every second of every day to an accuracy of ten billionths of a second
a day. These physicists have created an international standard, measuring a second as 9,192,631,770 vibrations of a Cesium 133 atom in
a vacuum. For more information about WWVB please see the NIST
website at
http://www.boulder.nist.gov/timefreq/stations/wwvb.htm
This allowance is typically enough for a frame wall with non-metallic
siding; however certain materials can reduce range even further. Metal
siding, stucco, and some types of glass can reduce signal range by as
much as 3/4 or more, compared to the 1/2 reduction typical of most
obstructions. It is possible to receive a signal through these materials,
however maximum range will be much less due to their tendency to
absorb or reflect a much larger portion of the sensor’s signal.
DETAILED SET-UP GUIDE
QUICK SET-UP GUIDE
Hint:
Use good quality Alkaline Batteries and avoid rechargeable
batteries.
1. Have the Wireless Weather Station and remote temperature sen-
sor 3 to 5 feet apart.
2. Batteries should be out of both units for 10 minutes.
3. Place the batteries into the remote temperature sensor first then
Wireless Weather Station.
(All remote temperature sensors must be started before the
Wireless Weather Station)
4. DO NOT PRESS ANY BUTTONS FOR 15 MINUTES.
In this time the Wireless Weather Station and remote temperature sensor will start to talk to each other and the display will show both the
indoor temperature and humidity, and an outdoor temperature. If the
Wireless Weather Station does not display both temperatures after
the 15 minutes please retry the set up as stated above. After both
indoor and outdoor temperatures are displayed for 15 minutes you can
place your remote temperature sensor outdoor and set your time.
The remote temperature sensor should be placed in a dry, shaded
area. The temperature sensor has a range of 330 feet. Keep in mind
that the 330 feet is in open air with no obstructions and that radio
waves DO NOT curve around objects. Actual transmission range will
vary depending on what is in the path of the signal. Each obstruction
(roof, walls, floors, ceilings, thick trees, etc.) will effectively cut signal
range in half.
Example: A Wireless Weather Station with a 330 feet range is mounted
on an interior wall, so that the signal has to pass through one interior
wall, one exterior wall, and across the 10 feet width of the room between the 2 walls. The first wall will reduce the range to 165 feet, and
the second wall will reduce the range to 87 feet. Factoring in the 10
foot room, this leaves a maximum of 77 feet of remaining signal range.

I. BATTERY INSTALLATION (When one temperature sensor is
being used)
1. First, insert the batteries to the temperature sensor (see “A. Remote Temperature Sensor” below).
2. Within 2 minutes of powering up the sensor, insert the batteries to
the Weather Station (see “B. Wireless Weather Station” below).
Once the batteries are in place, all segments of the LCD will light
up briefly. Following the indoor temperature and humidity, and the
time as 12:00 will be displayed. If they are not shown in LCD after
60 seconds, remove the batteries and wait for at least 60 seconds
before reinserting them. Once the indoor data is displayed user
may proceed to the next step.
3. After the batteries are inserted, the Weather Station will start receiving data signal from the sensor. The outdoor temperature should
then be displayed on the Weather Station. If this does not happen
after 2 minutes, the batteries will need to be removed from both
units and reset from step 1 and the signal reception icon is no longer
shown.

3. Observing the correct polarity install 2 AA batteries. The batteries
will fit tightly (to avoid start-up problems make sure they do not
spring free).
4. Replace the battery cover by sliding upwards. Be sure battery cover
is on securely.
B. Wireless Weather Station
1. Remove the battery cover (the cover has white writing on it).
2. Observe the correct polarity, and install two Alkaline AA batteries.
3. Do not press any buttons for at least ten minutes. If a button is
pressed before the indoor weather station has received information from the TX29U-IT sensor, no data will be received from that
sensor until reset.
4. Replace the battery cover.

reception icon*
* When the signal is successfully received by the Weather Station,
the icon will be switched on. (If not successful, the icon will not be
shown in LCD) So the user can easily see whether the last reception was successful (icon on) or not (icon off). On the other hand,
the short blinking of the icon shows that a reception is being done
now.
• If the signal reception is not successful on the first frequency
(915MHz) for 45 seconds, the frequency is changed to 920MHz
and the learning is tried another 45 seconds. If still not successful
the reception is tried for 45 seconds on 910MHz. This will also be
done for re-synchronization.

II. Start Up Sequence
A. Initial Start
1. Immediately after the batteries have been installed the LCD will
completely light up for a brief moment.
2. All information will then appear in normal mode, with “12:00” as the
default time and “SA.1” as the default date (2006 as the year).
3. The indoor temperature and humidity, and barometric air pressure
(as 29.92 inHg relative RH) will also be displayed.
4. There is a “satellite” icon that appears in the bottom portion of the
LCD, to the left of the outdoor temperature- this icon informs the
user that the indoor weather station is looking for signals from the
remote temperature sensor. Within five minutes the remote temperature should be displayed-if not, remove batteries from all units
and repeat battery installation, the remote temperature sensor first,
then the indoor weather station.
B. WWVB Reception
1. Once the batteries are installed in the Wireless Weather Station it
will automatically search for the WWVB signal. If it receives a good
signal (which is unlikely during daylight hours in most locations),
the WWVB reception indicator (looks like a tower icon) will flash.
The Wireless Weather Station requires five full minutes of good
reception to successfully capture the signal and set to the correct
hour, minute, second, month, day and year. If the signal reception
is not successful within ten minutes, the signal search will be
cancelled. Next reception will take place the next day.
2. The signal is sent from Ft. Collins, Colorado only and is similar to
an AM radio signal. Atmospheric interferences such as storms,
sunspots, and even sunlight will cause the signal to not travel as
far.
3. To maximize reception, place the Wireless Weather Station n in a
window facing Colorado, at least six feet from any electrical source
(computers, televisions, refrigerators, etc.). Do not move the indoor weather station while it is searching for the signal.
4. The time and date can be manually set. Once the signal is captured,
it will override any time and date set to the time zone selected.
5. Once the time and date are set, the Wireless Weather Station will
conduct a search every night at midnight and correct to the accurate time and date (Daylight Saving Time is automatic). If the signal
has been received in the past 24 hours, the reception indicator will
be displayed. After a successful reception, no more reception attempt would be made until the following day.

Note:
Barometric air pressure is usually reported as “relative air
pressure”. This reading is based on the combination of absolute air
pressure and altitude. In general, an increase in altitude will result in a
decrease in air pressure. Relative air pressure will make readings in
nearby locations relative to each other to allow for proper forecasting.
The absolute air pressure reading in the Weather Center cannot be
calibrated, only the relative air pressure.

press and hold the “SET” key for at least three seconds. You will see
then that the values will reset to the current temperature and corresponding time.
B. Multiple Remote Temperature Sensors
The WS-7394U-IT is able to receive signals from 2 additional temperature sensors. The following are instructions for the set-up of temperature sensor units with the WS-7394U-IT. These extra sensors can
be purchased through the same dealer as this unit.
1. Remove all the batteries from the receiver and sensor(s) and wait
60 seconds. During these 60 seconds, press any button 20 times
to discharge any excess power.
2. Insert the batteries to the first temperature sensor.
3. Within 2 minutes of powering up the first sensor, insert the batter-
ies to the Weather Station. Once the batteries are in place, all segments of the LCD will light up briefly. Following the indoor temperature and humidity, and the time as 12:00 will be displayed. If they
are not shown in LCD after 60 seconds, remove the batteries and
wait for at least 60 seconds before reinserting them.
4. The outdoor temperature from the first sensor (channel 1) should
then be displayed on the Weather Station. If this does not happen
and the signal reception icon is not shown, after 2 minutes, the
batteries will need to be removed from both units and reset from
step 1.
5. Insert the batteries to the second sensor as soon as the outdoor
temperature readings from the first sensor are displayed on the
Weather Station.
NOTE:
You must insert the batteries into the second sensor within 10
seconds of reception of the first sensor.
6. The outdoor temperature from the second sensor and the “channel
2” icon should then be displayed on the Weather Station. If this
does not happen after 2 minute, the batteries will need to be removed from all the units and reset from step 1.
GB
P.17
7. Insert the batteries to the third sensor as soon as the “channel 2”
icon and outdoor data are displayed on the Weather Station. Then
within 2 minutes, the channel 3 outdoor data from the third sensor
will be displayed and the channel icon will shift back to “1” once the
third transmitter is successfully received. If this is not happen, user
shall restart the setting up from step 1.
1. Weather Icons
There are 3 possible weather icons that will be displayed at various
times in the center of the indoor weather station.
NOTE:
You must insert the batteries into the third sensor within 10
seconds of reception of the second sensor.
IMPORTANT:
tiple sensors is not followed as described above. Should transmission
problems occur, it is necessary to remove the batteries from all units
and start again the set-up from step 1.
C. Viewing and Operating with Multiple Remote Sensors
a. To view the temperature of a different remote sensor press and
release the “CH” button. A shift from one “boxed” number to the
next should be observed in the OUTDOOR LCD.
b. The minimum and maximum temperature of the additional remote
sensor can be displayed by pressing the “OUT/+” button.
c. To reset the minimum and maximum temperature readings press
and hold the “SET” button for 3 seconds and that temperature record
for that remote sensor will be reset only.
Each remote sensor will have its own minimum and maximum values
stored.
D. Comfort Indicator for Indoor Temperature and Humidity
1. The comfort level indicator appears inbetween the indoor
tempearture and humidity.
2. The indicator will display a “happy-face” when the temperature is
between 68˚F and 79˚F (20˚C and 25.9˚C), and the humidity is
between 45% and 65%.
3. A “sad-face” will be displayed when the temperature and humidity
are outside the mentioned ranges.
E. Weather Forecast Icon and Pressure Trend Indicators
The weather forecasting feature is estimated to be 75% accurate, and
is based solely upon the change of air pressure over time. The WS7394U-IT averages past air-pressure readings to provide an accurate
forecast-creating a necessity to disregard all weather forecasting for
12-24 hours after the unit has been set-up, reset, or moved from one
altitude to another (i.e. from one floor of a building to another floor). In
areas where the weather is not affected by the change of air pressure,
this feature will be less accurate.
GB
Transmission problems will arise if the setting for mul-

a. Sunny-indicates that the weather is expected to improve (not that
the weather will be sunny).
b. Sun with Clouds-indicates that the weather is expected to be fair
(not that the weather will be sunny with clouds).
c. Clouds with Rain-indicates that the weather is expected to get worse
(not that the weather will be rainy).
1. The weather icons change when the unit detects a change in air
pressure.
2. The icons change in order, from “sunny” to “sun with clouds” to
“clouds with rain” or the reverse.
3. It will not change from “sunny” directly to “clouds with rain”, although
it is possible for the change to occur quickly.
4. If the symbols do not change, the weather has not changed (or the
change has been slow and gradual).
5. The sensitivity of the change in foreacst icon is set by the user in
section O of the Detailed Set Up Guide.
F. Weather Tendency Arrows
Pressure trend arrow
1. Along with the forecast icon there is a pressure tendency arrow.
2. There is one that points up (on the left side of the LCD) and one
that points down (on the right side of the LCD).
3. These arrows reflect current changes in the air pressure.
4. An arrow pointing up indicates that the air pressure is increasing
and the weather is expected to improve or remain good.
5. An arrow pointing down indicates that the air pressure is decreasing and the weather is expected to become worse or remain poor.
G. Barometric Air Pressure Reading
1. The actual barometric air pressure is displayed directly under the
weather forecast icon
2. The relative air pressure is calibrated by the user through the programming mode.
3. Please Follow the programming instructions in section N of the Detailed Set Up Guide to set this feature.

P.19
H. Air Pressure History Bar Chart
1. The bar chart indicates the air pressure history trend over the last
12 hours in 5 steps, 0h, -3h, -6h, -9h, and -12h.
2. The “0h” represents the current full hour air pressure recording.
3. The columns represent the “hPa” (0, ±2, ±4) at specific time.
4. The “0” in the middle of this scale is equal to the current pressure
and each change (±2, ±4) represents how high or low in “hPa” the
past pressure was compared to the current pressure.
5. If the bars are rising it means that the weather is getting better due
to the increase of air pressure.
6. If the bars go down, it means the air pressure has dropped and the
weather is expected to get worse from the present time “0h”.
Note:
For accurate barometric pressure trends, the Weather Station
should operate at the same altitude for example, it should not be moved
from the ground to the second floor of the house. Should the unit be
moved to a new location, discard readings for the next 12-24 hours.
This feature cannot be turned off.
VII. MOUNTING
Note:
Before permanently mounting, ensure that the Wireless Weather
Station is able to receive signals from the transmitters and WWVB
signal at the desired location. To achieve a true temperature reading,
avoid mounting the remote temperature sensor (or any sensor) where
direct sunlight can reach the remote sensor. We recommend that you
mount the remote sensor on a North-facing wall or under an eve. The
sending range of the remote temperature sensor is 330-ft (100m) however obstacles such as walls, concrete, and large metal objects can
reduce the range. Place all units in their desired location, and wait
approximately 15 minutes before permanently mounting to ensure that
there is proper reception. If the Wireless Weather Station loses the
signal from the remote sensor, it will display the last temperature reading for 15 minutes. After 15 minutes of not receiving any signals, the
remote temperature will display “- -.-”.
A. Mounting the Remote Temperature Sensor
The remote temperature sensor can be mounted in two ways:
• with the use of screws
• using the adhesive tape
1. MOUNTING WITH SCREWS
a. Remove the mounting bracket from the remote temperature sensor.
b. Place the mounting bracket over the desired location.
c. Through the three screw holes of the bracket, mark the mounting
surface with a pencil.
d. Screw mounting bracket onto the mounting surface. Ensure that
the screws are flush with the bracket.
e. Insert the remote temperature sensor into the bracket.
2. MOUNTING WITH ADHESIVE TAPE
a. With a nonabrasive solution, clean and dry the back of the mount-
ing bracket and the mounting surface to ensure a secure hold. The
mounting surface should be smooth and flat.
b. Remove the protective strip from one side of the tape.
c. Adhere the tape to the designated area on the back of the mount-
ing bracket.
d. Remove the protective strip from the other side of the tape.
e. Position the remote temperature sensor in the desired location, en-
suring that the Wireless Weather Station can receive the signal.

Note:
Mounting with adhesive tape is not recommended as a permanent mounting solution. Only use the adhesive tape during set-up
process.
B. Mounting the WS-7394U-IT Wireless Weather Station
The Wireless Weather Station can be mounted in two ways:
• with the table stand
• on the wall with the use of a wall hanging screw (not included)
1. USING THE TABLE STAND
The indoor weather station comes with the table stand already mounted.
If you wish to use the table-stand all that is required is to place the
indoor weather station in an appropriate location.
2. WALL MOUNTING
a. Remove the table-stand. To do this, pull down on the stand from
the rear and rotate forward.
b. Fix a screw (not included) into the desired wall, leaving approxi-
mately 3/16 of an inch (5mm) extended from the wall.
c. Place the indoor weather station onto the screw using the hanging
hole on the backside.
d. Gently pull the indoor weather station down to lock the screw into
place.
Maintenance and Care Instructions
A. Extreme temperatures, vibration, and shock should be avoided to
prevent damage to the units.
B. Clean displays and units with a soft, damp cloth. Do not use sol-
vents or scouring agents; they may mark the displays and casings.
C. Do not submerge in water.
D. Immediately remove all low powered batteries to avoid leakage and
damage.
E. Opening the casings invalidates the warranty. Do not try to repair
the unit. Contact La Crosse Technology for repairs.
TROUBLESHOOTING
Problem: The LCD is faint.
Solution:
1. Set the LCD contrast to a higher level.
2. Replace batteries.
Problem: No outdoor temperature is displayed.
Solution:
1. Remove all batteries, reinsert into the remote temperature sensor
first, then into the indoor weather station.
2. Place remote temperature sensor closer to the indoor weather
station.
3. Be sure all batteries are fresh.
4. No other interfering sources are being used (such as computer
monitors, TV sets, headphones, or speakers) in the vicinity. The
signal travels in a straight line, an electrical source near that “line”
may cause interference.
Problem: Temperature, humidity, or air pressure is incorrect.
Solution:
1. Check/Replace batteries.
2. If multiple remote sensors are in use, check location with corre-
sponding “boxed numbers.”
3. Move away from sources of heat/cold.
4. Adjust relative air pressure to a value from a reliable source (TV
radio, etc.).
5. The indoor weather station and remote sensors are calibrated at
the factory. If there is a consistent problem, please call La Crosse
Technology.
